DCI transports downlink control information for one or more cells with one RNTI.
The following coding steps, can be identified:
- Information element multiplexing
- CRC attachment
- Channel coding
- Rate matching
| Category | DCI Format | Description |
|---|---|---|
| DCI formats for scheduling of PUSCH | Format 0_0 | Fallback DCI. DCI format 0_0 is used for the scheduling of PUSCH in one cell. |
| DCI formats for scheduling of PUSCH | Format 0_1 | Indicates PUSCH scheduling. DCI format 0_1 is used for the scheduling of PUSCH in one cell. |
| DCI formats for scheduling of PDSCH | Format 1_0 | Fallback DCI. Indicates PDSCH scheduling and is used upon public message scheduling (such as paging and RMSI scheduling) and status change (such as BWP switch). DCI format 1_0 is used for the scheduling of PDSCH in one DL cell |
| DCI formats for scheduling of PDSCH | Format 1_1 | Indicates PDSCH scheduling. DCI format 1_1 is used for the scheduling of PDSCH in one cell |
| DCI formats for other purposes | Format 2_0 | DCI format 2_0 is used for notifying the slot format |
| DCI formats for other purposes | Format 2_1 | DCI format 2_1 is used for notifying the PRB(s) and OFDM symbol(s) where UE may assume no transmission is intended for the UE.. |
| DCI formats for other purposes | Format 2_2 | DCI format 2_2 is used for the transmission of TPC commands for PUCCH and PUSCH |
| DCI formats for other purposes | Format 2_3 | DCI format 2_3 is used for the transmission of a group of TPC commands for SRS transmissions by one or more UEs. Along with a TPC command, a SRS request may also be transmitted.. |
